Executive function (EF) skills are integral components of young children's growing competence, but little is known about the role of early family context and experiences in their development. We examined how demographic and familial risks during infancy predicted EF competence at 36months of age in a large, predominantly low-income sample of nonurban families from Pennsylvania and North Carolina in the United States. Using latent class analysis, six ecological risk profiles best captured the diverse experiences of these families. Profiles with various combinations of family structure, income, and psychosocial risks were differentially related to EF. Much of the influence of early risks on later EF appears to be transmitted through quality of parent-child interactions during infancy. Findings suggest that early family environments may prove to be especially fruitful contexts for the promotion of EF development.
执行功能 (EF) 技能是幼儿不断发展的能力的重要组成部分,但对于早期家庭环境和经验在其发展中的作用知之甚少。我们研究了在美国宾夕法尼亚州和北卡罗来纳州的一个以非城市家庭为主的大型、以低入家庭为样本中,婴儿期的人口统计学和家庭风险如何预测 36 个月时的 EF 能力。使用潜在类别分析,六种生态风险概况最好地描述了这些家庭的不同经历。具有不同家庭结构、收入和心理社会风险组合的概况与 EF 呈不同关系。早期风险对后期 EF 的影响很大程度上是通过婴儿期亲子互动的质量传递的。研究结果表明,早期家庭环境可能是促进 EF 发展的特别有成效的环境。
